In case the ignition switch does not change with the push of
a button, the key fob may have a low or fully depleted
battery. A low key fob battery can be verified by referring to
the instrument cluster, which will display directions to
follow.
NOTE:
A low key fob battery condition may be indicated by a
message in the instrument cluster display, or by the LED
light on the key fob. If the LED key fob light no longer illu-
minates from key fob button pushes, then the key fob battery
requires replacement.
In a situation where the battery is low or fully depleted, a
back up method can be used to operate the ignition switch.
Put the nose side of the key fob (side opposite of the emer-
gency key) against the START/STOP ignition button and
push to operate the ignition switch.
To Unlock The Doors And Tailgate
Push and release the unlock button on the key fob once to
unlock the driver’s door. Push the unlock button twice
within five seconds to unlock all doors, the tailgate and the
RamBox (if equipped). The turn signal lights will flash to
acknowledge the unlock signal. The illuminated entry
system will also turn on. NOTE:
The instrument cluster display or Uconnect Settings are
setup for driver door first, otherwise this will unlock all
doors.
To Lock The Doors And Tailgate
Push and release the lock button on the key fob to lock all
doors, the tailgate, and the RamBox (if equipped). The turn
signal lights will flash and the horn will chirp to acknowl
-
edge the signal.
Sound Horn With Remote Key Lock
This feature will cause the horn to chirp when the doors are
locked with the key fob. This feature can be turned on or
turned off.
NOTE:
Pushing the lock button on the key fob while you are in the
vehicle will activate the vehicle security alarm system.
Opening a door with the vehicle security alarm system acti -
vated will cause the alarm to sound. Push the unlock button
to deactivate the vehicle security alarm system.
Refer to “Instrument Cluster Display” in “Getting To Know
Your Instrument Panel” for further information.

REMOTE START — IF EQUIPPED
How To Use Remote Start
All of the following conditions must be met before the engine
will remote start:
• Gear selector in PARK
• Doors closed
• Hood closed
• HAZARD switch off
• BRAKE switch inactive (brake pedal not pushed)
• Battery at an acceptable charge level
• PANIC button not pushed
• Fuel meets minimum requirement
• System not disabled from previous remote start event
• Vehicle security alarm not active
Remote Start Abort Message
The following messages will display in the instrument

• Do not start or run an engine in a closed garage or confined area. Exhaust gas contains Carbon Monoxide
(CO) which is odorless and colorless. Carbon
Monoxide is poisonous and can cause serious injury or
death when inhaled.
• Keep key fobs away from children. Operation of the
Remote Start System, windows, door locks or other
controls could cause serious injury or death.

repeat the start sequence for a third cycle.
To Exit Remote Start Mode Without Driving The
Vehicle
Push and release the remote start button one time or allow
the engine to run for the entire 15 minute cycle.

SENTRY KEY
The Sentry Key Immobilizer system prevents unauthorized
vehicle operation by disabling the engine. The system does
not need to be armed or activated. Operation is automatic,
regardless of whether the vehicle is locked or unlocked.
The system uses a key fob, keyless push button ignition and
a Radio Frequency (RF) receiver to prevent unauthorized
vehicle operation. Therefore, only key fobs that are
programmed to the vehicle can be used to start and operate
the vehicle. The system cannot reprogram a key fob obtained
from another vehicle.
After placing the ignition switch in the ON/RUN position,
the vehicle security light will turn on for three seconds for a
bulb check. If the light remains on after the bulb check, it
indicates that there is a problem with the electronics. In addi-
tion, if the light begins to flash after the bulb check, it indi -
cates that someone attempted to start the engine with an
invalid key fob. In the event that a valid key fob is used to
start the engine but there is an issue with the vehicle elec -
tronics, the engine will start and shut off after two seconds. If the vehicle security light turns on during normal vehicle
operation (vehicle running for longer than ten seconds), it
indicates that there is a fault in the electronics. Should this
occur, have the vehicle serviced as soon as possible by an
authorized dealer.
All of the key fobs provided with your new vehicle have
been programmed to the vehicle electronics.
Key Programming
Programming key fobs may be performed at an authorized
dealer.
CAUTION!
The Sentry Key Immobilizer system is not compatible
with some aftermarket remote starting systems. Use of
these systems may result in vehicle starting problems
and loss of security protection.
